Hello!

When solving a quadratic equation, we should begin by confirming that the right side is equal to 0. The equation above, however, contains a 2 on the right side.

Therefore, the most logical first step would be to subtract 2 from both sides, leaving the ride side equal to 0.

I hope this helps!

Answer:

Option D is correct.

Step-by-step explanation:

$x^2-4x+16= 2$

In order to simplify the equation the first step is to subtract 2 from both sides to make 0 in the right side and converting it in standard form

$ax^2+bx+c=0$

therefore option D is correct

Identify the triangle PQR as isosceles (two sides of equal length), equilateral (three sides of equal length), or a scalene

Ipatiy [6.2K]

Answer:

Isosceles

Step-by-step explanation:

In order to figure what type of triangle this is out, we need to start by plotting the given points. That will help us visualize the triangle better and see if our conclusions make sense. (See attached picture).

Once we got the triangle, the strategy to follow is to use the distance between two points formula to see what the measurement of each side of the triangle is. This will help us determine if 2, 3 or none of the sides of the tirangle are the same.

The distance formula is the following:

$distance=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}$

so now we can find the desired distances, let's start with the distance between P and Q:

$|PQ|=\sqrt{(-4-0)^{2}+(9-8)^{2}}$

which yields:

$|PQ|=\sqrt{17}$

next, let's find the distance between P and R:

$|PR|=\sqrt{(-4-(-3))^{2}+(9-5)^{2}}$

which yields:

$|PR|=\sqrt{17}$

and finally the distance between Q and R:

$|QR|=\sqrt{(0-(-3))^{2}+(8-5)^{2}}$

which yields:

$|QR|=3\sqrt{2}$

As you may see from the result, only two of the three sides are the same, |PQ| and |PR|, so this will be an Isosceles triangle.

Patty sells pies to customers at a price of $16 per pie. She starts the day with $90 in her cash register. How many pies does Pa

Gala2k [10]

There are two ways you can do this question, you can one, subtract the 90 from 538 which should give you 448 then you can divide 448 by 16. Your answer should be 28 pies
